> An accidental lab transmission from bats to pangolins to humans (currently thought likely) is much harder to believe.
The pangolin hypothesis has been proposed by one research group, as far as I can tell. A whole-genome comparison found that the pangolin and human coronaviruses share 90.3% of their DNA. Civets, the source of SARS virus (SARS-Cov-1) shared 99%+ of its DNA with human SARS.
So far, the closest match to the human coronavirus has been found in a bat in China’s Yunnan province, which is where the research bats at both the Institute of Virology and Wuhan Centers of Disease Control were from.
> The lab-transmission theory is also dangerous because it's currently baseless in terms of hard evidence
Hard evidence will be extremely hard to come by in a situation like this. But based on circumstantial evidence, it's a leading theory. There's a reason why multiple Western intelligence agencies are reported to be considering it (including many that dislike Trump).
> It doesn't follow the rule of simple explanations.
Not true. In fact, it's one of the most straight forward explanation so far. A Beijing lab studying SARS in animal models experience 2 fatal accidental spillover events in 2004, infecting multiple humans with SARS.
If it was caused by a wet market, why have Chinese authorities started allowing them to operate again? That seems really risky, no?
> Yes, it could be true, but I hope you'll join me in really hoping it isn't
I agree. I hope it isn't, but it's imperative to nail down what caused this. Civilization may well depend upon it. Covid-19 has been an amazingly benign illness compared to what it might have been. We have to figure out if it was a wet market. If it was, it's incredibly foolish to allow them to continue to operate. If it was an accidental lab release, the world community needs to pressure the Chinese authorities to better regulate their labs.
> "It's from a chinese lab accident" is not the pseudo explanation we all need right now,
It's far, far less of a "pseudo-explanation" than the bat soup, which was taken as gospel for a while.
> Because I unironically think that if it turns out to be true it could cause a war.
It's possible, but I'm very skeptical we'd go to war for a variety of reasons. First, this is an accident we're discussing about, of ordinary scientific research. Not a bioweapons program, or an intentional release. That's very significant, obviously. Second, but Trump wants to avoid getting into war at almost any cost. His isolationism is part of his appeal to his base, and the one thing that I believe would cause them to desert him once the body bags started piling up and the initial patriotic fervor wore off. He knows this.
I'm personally more concerned about another deadly pandemic coming out of China than I am about a major war. Emerging diseases like SARS, H7N9, and now Covid-19 have all come from China in the past 20 years. We really need to get a handle on this, ASAP.
